Installation & Application Notes

Allow turbo to idle 2–3 minutes before shutdown — this circulates oil through bearings and prevents coking. Check oil feed and drain lines for blockages before fitting new turbo. Replace oil and filter when fitting new turbo — old oil contains metal particles.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
